Who is this choice for?

Families making mixed tuna fillings

Chunks are practical when tuna will be mixed with mayonnaise or vegetables for a sandwich, wrap or pasta pot. East Lancashire Hospitals NHS Trust suggests tuna with ingredients such as cucumber or sweetcorn in a packed lunch.

Children who prefer larger pieces

Steaks or fillets offer a more recognisable piece of fish than chunks. Break the tuna up and check it while preparing the lunch: the M&S tuna steak product page warns that bones may remain.

Families preparing lunch in a hurry

A no-drain format removes the step of draining liquid before making a filling. John West offers a no-drain tuna steak product; check the exact pack if you also have a preference for steak rather than chunks.

What should you check before buying?

Start with how the tuna will be served, then compare the exact pack’s ingredients and handling instructions.

PriorityWhat to checkYour needs
Piece size Check whether the pack contains chunks, steaks or fillets. Steaks and fillets retain larger pieces; chunks are easier to distribute through a mixed filling. For a tuna-mayo sandwich, I want pieces that mix through the filling. For a salad or rice pot, recognisable pieces may matter more.
Packing medium Read the ingredients and nutrition panel for the exact product. M&S lists 0.6g fat per 100g for its spring-water tuna steak and 17.3g per 100g for its olive-oil Ventresca fillets; those figures describe different products. Does spring water, brine or oil fit the filling I am making? I do not want to assume that products packed in different liquids have the same ingredients or nutrition.
Preparation Check whether draining is required and whether the pack size suits the amount you will use. No-drain is a format description, not a promise about piece size. On a busy morning, skipping a draining step would help. If I am mixing the tuna into pasta anyway, standard chunks may do the job.
Allergen and bones Check the current pack’s fish-allergen declaration and any bone warning. Inspect the tuna while preparing it; M&S warns that bones may remain in its tuna steak. I need to follow the child’s allergy plan and the school’s food policy, and check the filling before it goes into the lunchbox.
Opened tuna Follow the exact pack’s storage and use-by-opening instructions. The M&S steak and Ventresca fillet pages say to refrigerate leftovers and eat them within 2 days. If a pack provides more than one lunch’s worth, I need a plan for storing the unused tuna.
Fish variety The NHS says fresh and canned tuna do not count as oily fish. Consider oily-fish choices separately when planning fish meals. I do not want a tuna packed lunch to stand in for an oily-fish choice elsewhere in the week.

Packed-lunch mistakes to avoid

  • Treating chunks, steaks and fillets as interchangeable

    The format changes how the tuna works in a filling: loose chunks mix through mayonnaise, while steaks and fillets offer larger pieces.

    Decide whether the child wants distinct pieces or a mixed filling before choosing a format. Do not use “fillet” alone as a quality guarantee.

  • Counting canned tuna as oily fish

    The NHS says canned tuna does not count as oily fish, even though it is a fish option for a lunch.

    If oily-fish variety matters to your meal planning, consider that separately rather than relying on tuna to provide it.

  • Overlooking allergen information or bones

    Fish is an allergen, and the M&S tuna steak page warns that bones may remain. Both checks matter when preparing food for a child.

    Read the current pack, follow the child’s allergy plan and school policy, and inspect the tuna as you make the filling.

  • Guessing how to store an opened pack

    Opened-product instructions vary by pack. M&S says to refrigerate leftovers from its tuna steak and Ventresca fillets and eat them within 2 days.

    Check the pack before preparing more than one lunch’s worth, and follow its instructions for any unused tuna.

Common questions

Are tuna steaks or fillets a better choice than chunks for a packed lunch?

Not for every filling. Choose chunks if you will mix tuna into mayonnaise, pasta or a wrap; consider steaks or fillets if the child prefers larger, recognisable pieces. A no-drain format addresses preparation rather than guaranteeing either texture.

Does canned tuna count as oily fish?

No. The NHS says fresh and canned tuna do not count as oily fish, so consider oily-fish choices separately when planning fish meals.

What allergen information should I check?

Check the fish-allergen declaration on the exact pack and follow the child’s allergy plan and the school’s food policy. The M&S tuna steak and Ventresca fillet product pages both identify tuna as fish in their ingredients.

Should I check tinned tuna for bones?

Yes. The M&S tuna steak product page warns that bones may remain, so break up and inspect the tuna as you prepare a child’s filling.

What should I do with tuna left over after opening a pack?

Follow that pack’s storage instructions. The M&S tuna steak and Ventresca fillet pages say to refrigerate leftovers and eat them within 2 days; the steak instructions also call for unused contents to be transferred to a non-metallic container.
